In this context, electric vehicles car-sharing systems can play a significant role. This paper proposes a car-sharing system based on electric vehicles embedded in a Renewable Energy Community. To evaluate the performance of the proposed system, it has been designed for a municipality in southern Italy, assuming that renewable energy is produced by photovoltaic panels. Corresponding energy, environmental and economic benefits are evaluated by comparing different layouts, including conventional and electric vehicles, for the same fleet size and travelled distance. Assessments of energy sharing were made considering hourly and daily time intervals. A sensitivity analysis has been conducted considering four different sizes of the photovoltaic plant (from 15 kW to 30 kW). The obtained outcomes show the proposed system results in greater savings in primary energy and CO<sub>2</sub> equivalent emissions as the plant size increases, due to the energy shared among community members and the surplus electricity fed into the power grid.
